*E2 – The operator senses 2 obstructions before triggering a limit, it shuts down and alarms. Inputs with “Y” for “E2” will reset this condition.
All open commands override any other command (timer, close, safety, etc…)

Description
Enables maglock relay on close limit. Adds 1 sec delay on opening
On = Adds 3 sec delay with alarm before gate moves.
Sets functionality for terminal 9
Sets functionality for terminal 10
Probable Causes
Obstruction, Force too low, clutch too loose, motor not learned, Hall effect
Obstruction, Force too low, clutch too loose, motor not learned 2x , Hall effect
Manual release, bad - unplugged - out of adjustment - Hall Effect
Bad limit switch/nut and no chain on gate
Both limits triggered, Both circuits open, unit out of phase
No jumper, bad wiring, interference, needs reset, no communication
Set as single master, in between limits, press motor learn, hold H open cmd for 5 sec
